Experimental results and population response for selected chemicals

Funded under: FP7-JRC


In this report we present the experimental campaigns carried out to develop a comparison between contaminant thresholds at several levels focusing on population level, as well as the campaigns carried out to assess the speciation of a contaminant and hence on their bioavailability for the two selected metals in Thresholds: Cd and Hg. Due to some delays in the experimental phase (shifting of campaigns) as well as in the analysis of samples, in some cases the results are still at a preliminary stage. Therefore, improvements in this Deliverable are expected as the analytical results will be available at the laboratories of the Thresholds� partners. It is expected that these new results will be included in the Synthesis deliverable (D4.1.5). These experimental results also support the development of integrated fate and an effects model that allows the estimation of the main fluxes between compartments, i.e. air/water/sediments as well as the simulation of scenarios that could produce reaching a threshold (see D2.6.2). Under this approach, the role of the air-water interface and the biota (phytoplankton and bacteria) is being examined. This will help to determine levels of emissions that could produce a threshold point be reached.
